BEAM-CLAMP FOR PIPE-HANGERS.

V Specification of Letters Patent.

Application filed June 29, 1908.

Patented April 27, 1909.

Serial No. 440,848.

To all whom 'itrma'y concern:

Be it known that I, Join: II. DORAN, a citizen of the Unit-ed States,residing at Schenectady, county of Schenectady, and State of New York,have invented certain new and useful Improvements in Beam- Clamps forPipe-Hangers, of which the following is a specification.

The invention relates to such improvements and consists of the novelconstruction and combination of parts hereinafter described andsubsequently claimed.

Reference may be had to the accompanying drawings, and the referencecharacters marked thereon, which form a part of this specification.similar parts in the several figures therein.

Figure 1 of the drawings is a side elevation of the improved clamp andhanger secured to the lower web of an I-beam. Fig. 2 is an edge-view ofthe clamp and hanger detached from the I-beam. Fig. 3 is a top-plan viewof the clamp mechanismdetached. Fig. 4 is a view in perspective showin amodified form of the clamping-members etached.

The clamping mechanism comprises a pair of jaws, 1 and 2, ada ted toengage with the lower web 3 of-an I- earn 4. The jaws are.

provided with supporting shanks, 6 and7, the shank 6 being provided atits longitudinal edges with the upturned angle-flanges 8, and the shank7 with the similar flanges 9 so arran ed and proportioned that the shank7 an its flanges will loosely. fit the space between the flan es 8, onshank 6, whereby the shanks are ree to slide longitudinally one upon theother to enable the jaws to fit webs of different widths. The shanks areprovided with a slot, 10, along their longitudinal middle, so arrangedas to register one with the other. The pipe-hanger comprises a yoke, 12,and hanger-arms, 13 and 14, which arms are apertured at their lower endsto receive a pipe-supportin bar or pin, 15. The hanger is secured tot eclamping mechanism by means of a screw-bolt, 20, passed up throu h theregisterin slots 10 and inserted in t e screw-threade nut, 21. When theclam ing jaws have been adjusted upon the'web o the I-beam, they aresecured in pllace by clamping the shanks tightly toget er, which isaccomplished by the screwthreaded boltand nut. The screw-threaded boltalso asses through an a erture in the yoke of t e hanger and hol s thehanger tight to the shanks of the clamping jaws.

Similar characters refer to' The bar 15 may be made like an ordinarycotter-pin, as shown in Fig. 1, which can be easily inserted andwithdrawn from the apertured hangerarms. One of the pin a )ertures isshown .at 23 in Fig. 1. It is o vious that different sized hangers maybe used in connection with mechanism and adapted to approximately fitipes of predetermined size. A pipe 24 is s own which fills the spacebetween the hanger-arms 13 and 14.

The clamping jaws 1 and 2 and their shanks are referably formed fromheavy sheet metal ystamping or pressing in suitable dies; and whendesired, they can be made in modified form, as shown in Fig. 4-,.

in which form both the members are just alike, thereby requiring onlyone set of dies to form both members; whereas in the form shown in theother figures of the drawings where one shank is smaller than the otherso as to fit therein, a separate die is required for each member. Asshown in Fig. 4, the shanks have a single angle-flange, 30, along oneedge, instead of an angle-flange along the two opposite edges.Consequently it is necessary to make the single-flange shanks heavierthan those having an angle-flange on each of the opposite edges. Wherethe channel-formed shank is used, one shank fitting within the other, asshown, the clamping members can be made much lighter, as thechannel-form affords great strength in proportion to the weight of metalemployed.

It is obvious that a hanger of given size may be used to sup ort plpesof difiering sizes within certain imits, but hangersdiffering in sizemay'be employed for pipes differing largely in size. For example, acomparatively small sized hanger may be employed 'for the smaller sizesof pipe, and a arger hanger may be used for the larger sizes of pi es.The hangers being comparatively simp e and inexpensive, severaldifferent sizes may be provided, and the most suitable size used for anysize of pipe. The use of the cotter-pin makes it possible to easily andquickly attach the hanger to a pipe. The han or being connected with theclam ing mec anism by the screwbolt 20, which passesthrough a middleaperture in the yoke of the clamp, the hanger can be. rotated to any anlar position relatively. to the I- beam w ich adapts the constructionherein described to the support of pipes running in any angulardirection relatively to the line of the clamping the beam supports; Whendesired, the slots 10 in the shanks 6 and 7 may be made in the form of aseries of shorter slots, or bolt-holes, adapted to receive thescrew-bolt 20, thereby'afiording greater strength to the shanks.

By havingthe'an le-shank of each member which contains t e longitudinalslot 00- cupy a horizontal plane instead of a vertical plane, asheretofore practiced, the bolt which clamps the two members together canbe made to perform the additional function of sup orting thepipe-hanger, as shown, which ena les the operator to easily and quicklyadjust the pipe-hanger in a osition to hold the pipe at any desired ange, relatively, to the beam, and after the desired adjustment is onceobtained, to securely clamp the hanger in such angular position bytightening up the screw-bolt, which securely clamps the two shanks ofthe beam-clamp and the yoke of the pipe-holder together, so that theparts will be securely held in place.

What I claim as new and desire to secure by Letters Patent is' 1. Abeam-clamp for pipe-hangers, comprising two adjustable members, eachconsisting of an angle-iron shank rovided at one end with a clamping-jawan having one I of its angle-flanges in a horizontal plane andcontaining .a longitudinal slot, the slots registering one with theother, and means for securing the two members together and to apipe-hanger in differing positions, relatively, one to another.

2. A beam-clamp for pipe-hangers, comprising two adjustable members,each consisting of a'shank provided with oppositelydisposedangle-flanges, and at one end with a mid e-s ot, the shank of one memberbeing narrower than the shank of the other member, whereby the narrowershank may be inserted within the wider shank and slide longitudinally ofthe same with the respective angle-flanges of one member injuxtaposition with the angle-flanges of the other member, and the twoslots register with each other, and means for securin the two members indifiering positions re atively to each other.

In testimony whereof, I have hereunto set my hand this 16th day of June,1908.
